Low cost hydrogen production by anion exchange membrane electrolysis: a review
Anion exchange membrane (AEM) water electrolysis is a hydrogen production method that is achieved with an AEM, using electricity. One of the major advantages of AEM water electrolysis is the replacement of conventional ...
Electrospun zeolite-templated carbon composite fibres for hydrogen storage applications
The current study explored the application of the electrospinning technique to produce multi-hierarchical composites for hydrogen storage applications. Predetermined control of fibre porosity is expected to enable production ...
Development of efficient membrane electrode assembly for low cost hydrogen production by anion exchange membrane electrolysis
Electrochemical production of hydrogen from water using anion exchange membranes (AEMs) can be achieved with non-noble catalysts, other than traditional proton exchange membranes that use platinum group metals. Using ...
Gas crossover mitigation in PEM water electrolysis: hydrogen cross-over benchmark study of 3M's Ir-NSTF based electrolysis catalyst-coated membranes
In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated ...
Characterisation tools development for PEM electrolysers
Electrochemical impedance spectroscopy (EIS), current interrupt (CI) and current mapping (CM) were investigated as in-situ characterisation tools for PEM electrolysers. A 25 cm2 cell with titanium anode and carbon cathode ...
HySA infrastructure center of competence: a strategic collaboration platform for renewable hydrogen production and storage for fuel cell telecom applications
The Department of Science and Technology of South Africa developed the National Hydrogen and Fuel Cells Technologies (HFCT) Research, Development and Innovation Strategy. The National Strategy was branded Hydrogen South ...
Equivalent electrical circuit modelling of a Proton Exchange Membrane electrolyser based on current interruption
A Proton Exchange Membrane (PEM) electrolyser is characterised and modelled to identify important electrochemical effects. These electrochemical effects include the ohmic, activation, and concentration losses within the ...
A study of the loss characteristics of a single cell PEM electrolyser for pure hydrogen production
In this paper the losses of a proton exchange membrane (PEM) single cell electrolyser were investigated. The ohmic, activation and mass transfer losses are the most prominent losses in a PEM electrolyser. The Electrochemical ...
PEM electrolysis for hydrogen production: principles and applications
(CRC Press, 2015)
An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been ...
